There are apple cider vinegar capsules you can buy, sold by many different companies. Maybe you could take them with a meal to help your stomach? And at least it wouldn't hurt your mouth since they get swallowed so quickly.

I also threw out my ACV capsules. Sigh. I have a bit left in my bottle of Bragg which I use to make the salad dressing. Obviously the amount I get in that doesn't give me the MetEffect. I was trying to figure out a way to get more into my system. Maybe oil into my stomach first and then sip ACV water.

I've been thinking about your desire to get The Metformin Effect, Glenda; that is, how to increase your insulin sensitivity. Of course you are NOT diabetic so may not need the full Metformin Effect (the dosage varies depending on degree of insulin resistance, right?).

So if a full blown diabetic benefits from 2 T ACV per day, maybe 2 tsp (or less?) would be enough for you. Here's another experiment for you: try adding ACV vinaigrette twice a day (you could modify Nancy's recipe, I'm sure) and see how much you can tolerate. You might have to adjust the dose up and down a bit depending on your stomach and perhaps over time you can tolerate a bit more.

Funny it was just the opposite for me. I had been taking ranitidine (prescription zantac) 150 mg twice daily for years, and when I started intermittent fasting , one meal a day, and added ACV, I haven't even had to take one dose! No more heartburn. That may be due to IF, or may be due to ACV. I take mine ice cold in lemon flavored seltzer water. It's delicious.
